. THALER NEW YORK.

To all 'Lo/wm t may concern Be it known that I, DAvni S. KENNEDY, a citizen of thek United States, residing at Brooklyn, in the county of Kings and Sta-te of N ew York, have invented certain new and useful Improvements in Typographical Machines, of which-the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to typographicalmachines, such as linotype machines of' tlie general organization represented in Letters Patent of the United States to O. Mergentlialer, No. 436,532, wherein circulating matrices are released by escapementsf-rom a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce t-he type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

In such machines, the magazine is usually mountedin such manner that it may be quickly removed and replaced by another containing a different matrix font. Before removing the magazine, however', it is cus# tomary to lock the matrices therein; in fact, this is necessary when the eseapements are supported independently of the magazine, as otherwise the matrices would be free to escapetherefrom. Hence, the commercial machines are equipped with devices which will prevent the removal of the magazine until the matrices have first been locked therein, such as shown in the HOmans-. S. Letters Patent No. 829,868 and in my pending application, Serial No. 261,000. In the patent, in effecting the removal of the magazine, it is lifted out of engagement withthe escapements (which are supported in the machine frame) so that the looking devices are arranged to prevent the premature raising of the magazine; while in the application, before the magazine is removed, the-.escapeinents (which are pivotally connected to the magazine base-frame)- are lowered out of operative relation to the magazine, so that the locking devices are arranged to prevent the movement of the escapement as distinguislied from that of the magazine. In both Specification of Letters Patent.

cases, however, the locking of the matrices is effected by means of a transverse bar which .is inserted through the edge of the magazine in position to engage the upper ears of the lowermost matrices" and which as `it .is pushed home, disengages the above mentioned locking devices; and to unlock the matrices, the bar is withdrawn or detached from' the magazine and laid aside u ntil it becomes necessary to relock the matriees therein, the withdrawal of the bar allowingthe' locking devices toA act in preventing tlie removal of the magazine. In the use of this detachable matrix locking bar, considerable time is lost in interchanging the magazines, and in addition; the bar is -sometimes difficult to manipulate' and quite frequently becomes lost or misplaced, thus occasioning further delay. l

My present invention is intended to avoid the foregoing objections and consists in providing the magazine with a permanent matrix locking device which may he instantly moved to active or inactive position at wilf` and which is arranged to control the maga; zine locking devicesin such manner as to permit and preventgthe removal'V ofY the magazine as the matrices are locked? and unlocked, respectively. MyV invention further conteniplates an i'inproved'l forml of matrix locking baia-*one which; may be simple in construction, capable of easyand eflieient operation, and adapted for universaluse;

I-n the accompanying drawings, I have shown my invention merely ,in preferred form andl by way of example and as applied to the particular style of machine illustrated in the I'Iomans Patent, No. 829,868 but obviously many'V alterations and variations may bek made therein and' in its mode ofapplication which will be com'- prised-withinits spirit. Thus,it may be appliedto other forms oftypographicall ma chines, such as illustrated' iny my pending applicationabove mentioned, or' to any other classof machine w-herein it is desirable to lock the matrices in the'magazine. Generally speaking, I desire it' to be understood that I do not limit myself to any specific formvor- 'embodiment excepty in'so far as such limitations are specified-in the claims.

Referring to the drawings: 'Figure l is a top plan view of a magazine equippedwith my; invention and showing in Fiof. 2,

in particular the relation between the ma trix locking bar and the magazine locking latch;

Fig. 2 is a vertical section on the line 2-2'of Fig. 1 and showing the matrix lock ing bar in its inactive position;

Figs. 3 and 4 are vertical sections taken,

through the lower part of the magazine, as g and showing the matrix locking bar in different positions g` i Fig. 5 is a detail of a safety latchfor the matrix lockingY bar;

Fig. 6 is a top plan view ofthe lower part of the magazine, partly broken away to expose the matrix locking bar and. certain details;

Fig. 7 is a section on the line 7-7 of Fig. 6; and Y Fig. 8 is a bottom plan view of the cover plate forming the lower section of the up.

' projecting ears ofthe matrices engage, the

upper magazine plate having the detachable reinforced cover section A2 as usual, and the lower magazine plate having the openings A10 to receive the grooved portions of the esca-pement supporting bar C2. The magazine is removably supported upon the base frame B which is pivoted at its upper end so as to be swung upwardly to raise the magazine out of engagement withY the escapements and to locate it above the assembler entrance G in position for removal, this upward swingingV of the base frame being effected by the rotary cams Bl'adapted to cooperate with rollers on the machine frame andV fixed to the opposite ends of the rock shaft B2 journaled in the'base frame and rotated Vby the handle B3.- One of the cams B1 is formed on its inner face with the lug or stop shoulder B4 adapted" in the normal or lowered position ofthe base frame to be engaged by the rear end of the spring actuated latch or lever C3 centrally pivoted to the escapement supporting bar C2 or some other relatively fixed part of the machine.v

The foregoingY parts and their manner of operation are well known and are illustrated and described'in the above Homans Patent No. 829,868. lIn the present instance,

- l therefore, the-latch C3, which'locks the lifting cams against rotation, serves to prevent the removal of the magazine and the preliminary'disengagement or separation of the escapements until the matrices are locked in the magazine.

As before stated, my invention contemplates a matrix locking'device which is permanently mounted on the magazine and which may be instantly moved to active or inactive position at will. In the present instance, such device is in the form of a Hat tion A2 and havin@r their free ends beariner D C upon extended portions A5 projecting into said recesses, which latter are preferably closed by cover plates AG. The springs thus confine the bar in its groove while permitting it Ato be moved in the three directions stated.

As shown in Fig. 1, the relative arrangement of the latch C2 and the bar E is such 'that the rear end of the former is located in the path of movement of the latter; hence, by a slight longitudinal shifting of the bar to the left, the latch maybe disengaged to permit the raising of the magazine for removal. However, means are provided whereby the longitudinal shifting of the bar will move it sidewise or laterally into the magazine for engagement with its matrices. Such means, in the form illustrated, consist of a plurality of buttons or protuberances A7 carried by the magazine section A2 and iitting in corresponding recesses or depressions E2 vformed in the upper side of the bar Ef l/Vhcn, then, the bar E is shifted longitudinally, its recesses E2 will be disengaged from the buttons A7, (see dotted line showing in Fig. 7) producing in effect a cam action which displaces the bar later- \ally or sidewise and projects it into the magazine. Fig. 2 shows the bar in its inactive position and located out of the path of the matrices so as to permit them to pass freely from the magazine; while Fig. 3 shows the bar projected into the magazine'in v)osition to engage the u) er ears of the lowermost matrices and thus to prevent their escape. By shifting the bar longitudinally in opposite directions, therefore, the matrices in the magazine may be locked and unlocked respectively, it being noted that n the bar is arranged to .disengage the magazine locking latch C3 as it is moved to active position and to permit the engagement or reengagement of said locking latch as it is restored vto inactive position. The Ybar is preferably formed with a grip portion ES to facilitate its manual operation. Y 'A In these machines, before separating the magazine and eseapements, it is desirable to push the matrices back within the magazine in order to disengage them from the escapements. To effect this result, means are provided whereby the longitudinal shifting of the matrix locking bar to active position will also effectv its edgewise displacement rearwardly ofthe magazine, such action following preferably the lateral displacement before described. In the present instance, such means comprise rollers A8 j ournaled in the magazine/section A2 andengaging in recesses in the forward edge of the bar E, which recesses are formed-so as to present straight surfaces E3 and-inclined or cam surfaces E4 (Fig. 8). Consequently when the bar is shifted'to the left, the rollers A8 first track idly upon the straight surfaces E, duringwhich period the bar is shifted sidewise or laterally, and thereafter the rollers engage the inclinedl or cam= surfaces E4, which by the continual shifting of the bar displace it bodily edgewise rearwardly of the magazine, as indicatedl by the dotted lines i1i- I4`igs. Gandf 8, it being pointed out Vthat the bar is formed in its rearedge with alongitudinal notch'or recess E5 which permits such edgewise displacement (Fig. 4). Then the bar is shifted to the right for returnv to inactive position, it is positively moved forward of the magazine in position to enter the groove A3 by means of the cooperating cam surfaces E6 and A formed on the barv and the magazine section A2 respectively, see F ig. 8. p

The operation of the matrix locking bar may be summarized as followsz'The first or initial longitudinal shifting of the bar to the'left causes' it to be moved from the position shown in Fig. 2 tofthat shown inFig. 3, such movement being effected by the disengagement of the buttons A7 and the recesses E2. The remaining'or final longitudinalshifting of the bar causes it to beV moved from the position shown in F ig. 3 to that shown inV Fig; 4, due tofthe engagement of the rollers A3 and the inclined or cam surfaces E4, this final shifting of the barv also rocking the latch C3 about its pivot to disengage it' from the stop-shoulder B4 on the lifting caml B1. In this condition of the parts, the matrices are pushed back and locked within the magazine and the latter is free tovbe raisedi'out of engagement with the escapements and located in position for removal, it' being noted that? the matr-ix locking bar E andl the magazine locking latch are arranged to be disengaged as the magazine is raised'by'the upwardswinging of its suppoiting'base frame. IVhen a new magazine iis-substituted, thesame condition of the parts obtains until the matrix locking bar is vshiftedto the right to release the matrices. Iuring such-'rightnard shiftingv of the bar,.the cam surfaces EG and A cause it tovbe moved-forwardly from the position shown in Eig. 4 to that shown in Fig. 3 and the continued shifting of the bar in the same direction brings its recesses E2 into `gegistryy with the buttons A7, whereupon the sprngs'El draw the bar back within the recessA3 from the'position shownfin Eig, 3 to that-shown in Fig. 2. The matrices are thus unlocked andthe magazine made ready for use by avslight4v longitudinal movement of the bar E to the right, this movement at the samel time disengaging the bar from the latch C3 and allowing the latter under the action-z of its spring tov rengage the .stop shoulder B* to lock the magazine against removal;

To insure the retention of" the bar E in its longitudinallyY shifted position, the magazine section- A2 is provided with a springactuated safety catch or dogy F (Figs. 5 and 8) arranged'to snap'into a* recess ET in the end'of the bar when in its extreme locking position;` Tlie latch isl disengaged by hand as the bar: is shifted tothe right to unlocking position;

Itv is noted' that the bar E is entirely inclosed within-the groove A3 andihence offers no obstruction to the use ofthe magazine. In addition, the form and' arrangement of the bar is such that magazines equipped with it' maybe readily usedin machines having magazines equipped with theold form of locking bar. In other words, itis possible to employ in the commercial machines a maga-` zine equipped with the old detachable locking bar or a magazine equipped with my improvedI locking bar thus permitting a free interchange of! magazines, which is of great advantage-inE View of the number of machines and old magazines now in use.

lVhile Ii have herein shown and described the matrixv locking bar in cooperation witha magazine` locking device, it isvpointed out that the bar mightl be employed alone to goed@ advantagefor in combination with devices to effect its movements automatically instead ofmanually, as would'be desired for instance in a machine employing a plurality of movable magazines. As previously stated, I= havev shown my improvements merely in preferred for-m and by way of example, andobviously many changes, modifications and adaptations will suggest themselves-to those skilled in the art without departing' from the scope of my invention Having thus described my invention, its construction and mode of operation, what I' claim'and desire to secure by Letters Patent of the'United States is as follows:
